PEMA
™
Protea-Equipped
Media Amplifier
PEMA™ sets a new industry benchmark for value-engineered
zone sound systems. By seamlessly merging our powerful,
open-architecture DSP functionality paired amplifier performance inside a two-rack space unit, PEMA lowers overall
system cost, occupies less space, improves energy efficiency,
and both speeds and simplifies system installation and
programming. Four and eight amplifier channel versions
are available at both 125 and 250 Watts per channel.
Full 96kHz performance is available on 32-bit SHARC
processors for utterly transparent audio.
As a member of the respected Protea™ DSP lineage,
PEMA is remarkably easy to program and deploy. All set
up is accomplished using standard 10/100 Ethernet
protocol and our Protea™ ne Software on a PC platform.
Hot-plug DSP placement allows users to insert any function
into any channel block, even when running live audio.
Automatic DHCP network IP configuration reduces network
set up time. Lockable front panel controls and multi-level
software security with password access guarantee a tamperproof audio system.
PEMA changes the way consultants and integrators approach
sound system design. With only the addition of input sources
and output speakers, PEMA delivers an elegant solution with
less cabling, less rack space, and less installation time, using
proven DSP and amplifier technology that will awe clients
with its simplicity, sophistication, and reliability.

control and serial data control
• External control via Ashly standard wall remotes, Ashly
Ethernet wall remotes or Ashly Remote iPad® App
• Level control via variable DC control voltage
• Stand-By mode activation via contact closure
• Multi-level Security
• Safety/Compliance: cTUVus, CE, FCC, RoHS
In addition to DSP algorithms such as FIR filter capability,
ambient noise compensation, advanced automatic feedback
suppression, automatic mixer, and a full complement of
filters, EQs, delays, and the like, PEMA offers DSP control of
the amplifier functionality as well: selection of bridge-mode
operation, HPF settings for constant voltage system networks,
stereo-linking of channel pairs, MIC/LINE/TEL-PAGE functions
on channel 1, full control of ducking priorities, and full-range
remote-gain control capability.
PEMA’s I/O count and formats are ideal for small to mid-sized
installations. Each variant has eight balanced input channels
that are software selectable for mic or line levels. The first
channel may also be set for a transformer isolated, TEL-PBX
level. Additionally there are eight pairs of summed-mono RCA
connectors optimized for consumer line level devices. Eight
preamp auxiliary outputs allow integrators to route signals
from the matrix mixer to anywhere the system requires.
* The standard low impedance (Low-Z) 125W models also double as 125W constant voltage models.
† Ashly PEMA Series Amplifiers must be ordered complete as either Low-Impedance (Low-Z) or as Constant Voltage models.

Pema 4125
The powered digital signal processor shall consist of eight inputs and four power amplifier outputs with the ability to assign any input to any output. Each input channel shall include a summed stereo (RCA, +11dB
maximum) and mic/line gain stage (3-pin Euroblock, +21dB maximum) capable of 0, +20dB, +40dB, and +60dB of gain with +15V phantom power when selected. Summed stereo input impedance shall be 3.16k Ohms
unbalanced and mic/line input impedance shall be 4.8k Ohms active balanced. Channel One shall include a transformer-isolated TEL-PBX select. Each input and output shall have individual mute capability. Each input
and output shall have six processing blocks configurable for Dynamics (ambient noise compensation, compressor/limiter, auto-leveler, ducker, gate), Gain (including Group VCA and remote gain), Equalization (FIR
filters, 31-band graphic, parametric x 10, feedback suppressor), Crossover, Delay, Metering, and Signal Generator (sine wave, pink noise, white noise). The routing stage shall allow the user to assign an input to any or
a combination of outputs and separately adjust how much signal level goes to each output (matrix mixer). The matrix mixer shall also have selectable gain-sharing automatic mixing capability. Each input stage shall
have an additional preamp output (post DSP) on the back panel (3-pin Euroblock). Four powered outputs shall deliver 75W @ 8 Ohms, 125W @ 4 Ohms (7.62mm Euroblock), and channel pairs can be bridged for
250W @ 8 Ohms. Frequency response shall be ±1dB 20Hz to 20kHz. Signal-to-Noise shall be greater than 102dB, 20Hz – 20kHz unweighted. LED indicators shall show signal level (-18, -12, -6), clip/mute, bridge, over
temperature and over current conditions. Output levels shall be adjusted by front panel volume controls when enabled. Full programming and control of the unit shall be from the rear panel RJ-45 jack connected to a
10/100BASE-T Ethernet LAN connected to a PC running Ashly’s Protea NE Software. Thirty internal presets (scenes) shall be standard and four scenes shall be accessible via contact closure. The powered digital processor shall have Cobranet and Dante factory option. A back panel contact closure shall place the unit in “Standby” reducing power consumption when idle. The power switch shall be enabled or disabled as needed. Five
password user names and eight levels of security shall be available. A temperature dependent speed-controlled axial fan shall maintain the correct operating temperature. The unit shall weigh 18.5 lbs net and mount
